How to set the Y-Axis in DCA Wrangler

To give you greater control when editing declines in the DCA Wrangler, we have added an option to lock the Y-Axis at a specific maximum. The ability to lock this axis gives us some neat follow on features.

  1. Fine control with the interactive decline curve editor in Single-Well mode.
  2. Ability to compare many declines with the same scale on the plot in Multi-Well mode.

New Result Tables workflow in DCA Wrangler

We’ve added a slick new feature to help you manage all that Well Decline and Type Curve data in Spotfire. Result Tables in the DCA Wrangler represent the current working set of data produced by the DCA Wrangler. In this article, I will show you how to:

  1. Add multiple Result Tables of the same type and target each separately.
  2. Compare different decline assumptions for the same set of wells – with the ability to tweak parameters.

Using Spotfire for Decline Model Identification

A common reservoir engineering workflow is identifying production decline model(s) suitable for the production profile of wells or reservoirs; and quite frequently, asset management experts are tasked with calculating values of determining factors, and applying those factors in decline curve equations to establish forecast methodologies applicable to different periods in an asset’s production history.

Arps Type Curve in Spotfire in 20 minutes

Type curves are an important part of resource assessment of an oil and gas asset. In this workflow, well declines are aggregated to determine typical behavior of a well ensemble. These well ensembles usually reflect a reservoir or set of analog reservoirs that will help determine characteristic behavior. In this post, we will build a decline model for the group of wells that is called a type curve. The type curve will capture the production rate forecast for a single “average” well and so can be used to determine Estimated Ultimate Recover (EUR). Best yet, we’ll do it in 20 minutes. A little longer than GEICO, but you’ll save so much more money.
